// then use it by need
Use in html, see what your can use in CDN: unpkg
<-- use what you want -->

(url: String|Image|File|FileList|Blob) => Promise<Object: {width, height}>
(imgFile: File|Blob, compressOptions: CompressOptions) => Promise<Blob|String>
var compressTypes = [
'scale', // Resize the image by `options.scale`
'fixedWidth', // Set the width of the image to a fixed value -- `options.imageSize`
'fixedHeight', // Set the height of the image to a fixed value -- `options.imageSize`
'fixedSize', // Set the smaller between width and height of the image to a fixed value -- `options.imageSize`
]
/**

* @property { Number } compressOptions.scale default to 1
* @property { Number } compressOptions.imageSize default to 0
* @property { String } compressOptions.imageType default to default to the type of `imgFile` or 'image/png'
* @property { Number } compressOptions.quality default to 0.8
* @property { Boolean } compressOptions.toBlob default to true
* */
var defaultOptions = {
compressType: compressTypes[0], // Compress type, options: `compressTypes`
scale: 1, // Scale factor, works when compressType is `scale`
imageSize: 0, // The fixed value of size, works when compressType is `fixedWidth`, `fixedHeight` or `fixedSize`. If imageSize is 0, it means convert to naturalSize
imageType: imgFile.type || 'image/png', // The mine type of image returned
quality: .8, // Compress quality, works when imageType is `image/jpeg` or `image/webp`
toBlob: true, // If it is false, the promise returned will be resolved with a base64 string
